Do you have the 1/2" shaft hubs for the jointer and the jig saw?

These are the hubs that came with it, 2 have a 1/2 inch hole and the other 2 have a 5/8? hole

The two with 1/2" bores and 5 grooves each mount on the jigsaw and jointer input shafts.

The longer of the other two mounts on the top headstock shaft with the smaller end facing the headstock.

The remaining hub mounts on the idler shaft.

The coupler engages the 4 grooves on the driven end, and the 5 grooves on the driver end. The driver end is spring loaded out so as to disengage if the coupler becomes 'loose' due to headstock drifting(or whatever cause).

Make sure the set screws are centered on the flats.

Thanks JPG, you are always very insightful!!

I have started to lubricate everything today and when trying to run through the speeds it is quite difficult to turn the handle. It does go through all seeds. Looking down from the top it looks like something is bent in the speed control assembly.

I do hope the shafts are rotating as you attempt to change the speed control knob.

What are are you 'oiling'?

Hopefully between the shafts and the sliding sheaves(both idler shaft and motor shaft).

As for the cocked speed control, I think disassembly is called for so as to ascertain it's cause.

Truth be told, a complete teardown would be both educational for you and a prudent thing for the machinery. These animals tend to get neglected(who pays attention to the 'lubricate every 10 hours thingy'?). Doing so will reveal any other idiosyncracies.

I realize you are likely chomping at the bit to make sawdust etc., but, time spent now 'refurbing' and coming to understand the beast will pay off many times in both reliability and self satisfaction. I think your location will mean you are the sole member of the 'support team'(besides us here that is).

Good Boy posting pix!!!!

That seller sure does have some parts that appear to be in good condition. Thank for the link.

I put a few drops of oil in the holes on the motor and idler shaft. It does run through all speeds when the motor is running.

I am definitely keen to start making sawdust!!! but at the same time a good service and possibly replacement bearings would be a good idea. The support from everyone here is fantastic.

Cheers

I have removed the speed controller tonight and found that the threaded shaft has a small bend in it, about 0.5mm. It appears to be putting a lot of pressure on the thread on the speed changer assembly and has distorted the threads/groves on the aluminum part. Is this damaged beyond usage? I think I will be able to straighten the shaft on the threaded rod.

It is typical for this set of parts to show signs of wear and tear. The bent shaft is the result of longs years of use and some damage due to misuse. Frequent cleaning and lubrication coupled with never turning the speed control unless the motor was turning would have prevented most of it.

In other words "this is normal".

It can be fixed by straightening the shaft. The wear on the teeth could be a lot worse. What you have, if straight, will work for a long time if used properly.

Browse the forum, you'll find several threads that discuss exactly your current situation.

You may find some help in http://www.shopsmith.com/ss_forum/viewt ... 90#p185690 which should help getting you very familiar with the machine and what needs attention.

The two posts always on the top of the Maintenance and Repair section will help you in performing the various repairs, updates and routine maintenance and prevent other issues from occurring at all, if followed.

Bill Mayo (who will be out for surgery soon) developed a method of strengthening the speed control assembly by replacing the roll pin with (10-32 X 2 1/2" allen head bolt, 2 star washers & nylock nut), but it doesn't replace proper frequent lubrication of the speed control sheave which the quadrant moves as well as the contact surface of the quadrant on the button in it interfaces with. Well worth considering since you are in Australia.

Also the floating sheave on the motor itself needs frequent lubrication and cleaning.

You will find all that and more in the forums.
